> RBF: The operation of renaming a multi-subcluster directory to a
> single-cluster directory should throw ioexception
> ------------------------------------------------------------------------------------------------------------------
>
> Key: HDFS-16954
> URL: https://issues.apache.org/jira/browse/HDFS-16954
> Project: Hadoop HDFS
> Issue Type: Bug
> Components: rbf
> Affects Versions: 3.4.0
> Reporter: Max Xie
> Assignee: Max Xie
> Priority: Minor
> Labels: pull-request-available
>
> The operation of renaming a multi-subcluster directory to a single-cluster
> directory may cause inconsistent behavior of the file system. This operation
> should throw exception to be reasonable.
> Examples are as follows:
> 1. add hash_all mount point `hdfs dfsrouteradmin -add /tmp/foo
> subcluster1,subcluster2 /tmp/foo -order HASH_ALL`
> 2. add mount point `hdfs dfsrouteradmin -add /user/foo subcluster1
> /user/foo`
> 3. mkdir dir for all subcluster. ` hdfs dfs -mkdir /tmp/foo/123 `
> 4. check dir and all subclusters will have dir `/tmp/foo/123`
> `hdfs dfs -ls /tmp/foo/` : will show dir `/tmp/foo/123`;
> `hdfs dfs -ls hdfs://subcluster1/tmp/foo/` : will show dir
> `hdfs://subcluster1/tmp/foo/123`;
> `hdfs dfs -ls hdfs://subcluster2/tmp/foo/` : will show dir
> `hdfs://subcluster2/tmp/foo/123`;
> 5. rename `/tmp/foo/123` to `/user/foo/123`. The op will succeed. `hdfs dfs
> -mv /tmp/foo/123 /user/foo/123 `
> 6. check dir again, rbf cluster still show dir `/tmp/foo/123`
> `hdfs dfs -ls /tmp/foo/` : will show dir `/tmp/foo/123`;
> `hdfs dfs -ls hdfs://subcluster1/tmp/foo/` : will no dirs;
> `hdfs dfs -ls hdfs://subcluster2/tmp/foo/` : will show dir
> `hdfs://subcluster2/tmp/foo/123`;
> The step 5 should throw exception.
